DDL &DML Queries in SQL PLUS

AIM: To implement the DDL Queries in SQL PLUS.

DDL Queries:

1. Command: CREATE TABLESyntax:

CREATE TABLE table_name(Column_name[ owner_name ] table_name);

2. Command: INSERT INTOSyntax:

INSERT INTO table_nameVALUES (value1, value2 ...)

3. Command: SELECT FROMSyntax:

SELECT column_name(s)FROM table_name

4. Command: ALTER TABLESyntax:

ALTER TABLE [owner_name ] table_name[ADD column_namedatatype attributes][MODIFY {column_namedatatype | column_constraint}]

5. Command: UPDATESyntax:

UPDATE table_nameSET column_name = new_valueWHERE column_name = some_value

6. Command: DROP TABLESyntax:

DROP TABLE table name;

RELATIONAL OPERATORS & AGGREGATE FUNCTIONSAIM:To create a table and manipulate the table using logical and comparison operators.

SQL Aggregate FunctionsSQL aggregate functions return a single value, calculated from values in a column.

AVG() - Returns the average value COUNT() - Returns the number of rows MAX() - Returns the largest value MIN() - Returns the smallest value SUM() - Returns the sum

SQL AVG() SyntaxSELECT AVG(column_name) FROM table_name

SQL COUNT(column_name) SyntaxThe COUNT(column_name) function returns the number of values (NULL values will notbe counted) of the specified column:SELECT COUNT(column_name) FROM table_name;

SQL COUNT(*) SyntaxThe COUNT(*) function returns the number of records in a table:SELECT COUNT(*) FROM table_name;



SQL COUNT(DISTINCT column_name) SyntaxThe COUNT(DISTINCT column_name) function returns the number of distinct values ofthe specified column:SELECT COUNT(DISTINCT column_name) FROM table_name;The MAX() Function

The MAX() function returns the largest value of the selected column.SQL MAX() SyntaxSELECT MAX(column_name) FROM table_name;The MIN() Function

The MIN() function returns the smallest value of the selected column.SQL MIN() SyntaxSELECT MIN(column_name) FROM table_name;The SUM() Function

The SUM() function returns the total sum of a numeric column.SQL SUM() SyntaxSELECT SUM(column_name) FROM table_name;



RESULT:Thus the Relational Operators and Aggregate Funcitions in SQL PLUS areimplemented.

PROCEDURES AND FUNCTIONSAIM:To study and execute the procedures and functions in PL/SQL.

SYNTAX:PROCEDURE:create or replace procedure [parameter list] is;begin(executable statements)[exception] (exception handlers)end;

A procedure has two parts namely, specification and body. The procedurespecificationbegins with keyword procedure and ends with procedure name or parameter list.Theprocedure body begins with keyword is and ends with the keyword end. It can alsoincludedeclarative, executable and exceptional parts with in the keywords are and end.Syntax toexecute a procedure is.SQL> exec (parameters);FUNCTION:A function is a subprogram that computes a value. The syntax for creating a functionisgiven below.create or replace function [argument]returndatatype is(local declaration)begin

where arguments can be in, out or inout.Similar to a procedure, a function also has two parts namely, the function specificationandthe function body. The function specification begins with the keyword function andendswith the return clause. The function body begins with the keyword is and ends withthe keywordend.

CURSORSAIM:To study the PL/SAQL programs and to write the PL/SAQL programs using cursors.DEFINITION AND SYNTAX:1. PL/SQL:PL/SQL stands for procedural structural language/SQL. PL/SQLextends SQL byaddingcontrol structures found in other structural languages.PL/SQL can be used in the Oraclerelational database in the Oracle server and in the client sideapplication developmenttools.SYNTAX:APL/SQL block can divide into three parts namely,i) Declarative part,ii) Executable part, andiii) Exception handling part.

The order is shown below:DECLAREDeclarationsBEGINExecutable statementsEXCEPTIONHandlersEND;



Objects can be declared in declarative part, which can be used in executablepart for furthermanipulation. All procedural statements are included betweenthe BEGIN and ENDstatements. Errors that occur during the exception are handled by theexception handlers.2. ATTRIBUTES:Attributes allows us to refer data types and objects from database. PL/SQLconstants andvariables have attributes. The following are the types of attributes supported bythePL/SQL, %type %row type %type:

%type is used when declaring variables that refer to database columns.SYNTAX:Variablenametablename.Column %type;%rowtype:%rowtype attributes provides a record type that rapresents a row in the tablw. Therecordcan store an entire row of data selected from the table or fetched by a cursor.SYNTAX:Variablenametablename %rowtype;3. CURSORS:Oracle allocates a memory known as the context area for the processing of theSQLstatements. A cursor is a pointer or handle to the context area. Through the cursor,aPL/SQL program can control the context area and what happens to it as the statementisprocessed.



The three types of the cursors are Static cursors Dynamic cursors REF cursors

Static cursors are the ones whose select statements are known at the compile time. Thesearefurther classified into Explicit cursors Implicit cursors

EMBEDDED SQL JDBC ODBC CONNECTIONAIM:

To write a JAVA program to implement embedded SQL.ALGORITHM:1. Start the program.2. Create Database using Oracle with the following fields,3. Next create the DSN by the following steps: Select Administrative Tools option from Control Panel. Then click on DataSource(ODBC), which displays a dialog box named ODBC

DataSourceAdministrator in which click Add button.4. Go to command prompt and type the JAVA program.5. Compile and run the program.



SQL> Create table jdbc(2 Rno number(5),3 Name varchar2(15),4 Dept varchar2(10)5 );

import java.io.*;import java.sql.*;public class jdeg {public static void main(String args[])throws IOException {BufferedReader br=new BufferedReader(new InputStreamReader(System.in));String rollno,nam,dep,mark;System.out.println("Enter the values(rno,name,dept)to insert into table");rollno=br.readLine();nam=br.readLine();dep=br.readLine();try{Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");Connection con=DriverManager.getConnection("jdbc:odbc:VEERA","mca","manager");Statement st=con.createStatement();st.executeUpdate("insert into jdbc values('"+rollno+"','"+nam+"','"+dep+"')");ResultSet rs=st.executeQuery("select * from jdbc");System.out.println();System.out.println();System.out.println("RNO\t\tNAME\t\tDEPT");System.out.println("***\t\t****\t\t****");while(rs.next()){System.out.print(rs.getString("rno")+"\t");System.out.print(rs.getString("name")+"\t\t");System.out.print(rs.getString("dept")+"\t");System.out.println();}}catch(Exception e){System.out.println(e);}}
